vision of a simple and inexpensive attach-v ment, readily applicable to*any existing water-cooled internal combustion engine, whereby saidengine may be efficiently operated by kerosene, as a fuel, insubstitution for the usual'gasolene.

The more particular objects of the invention'yitogethe with-meanswhereby the same maybe carried into effect, will best be understoodfromthe following description of one form or embodiment thereofillustrated in the accompanying drawings. It will, however, beunderstood that the particular construction and arrangement describedand shown have been chosen for illustrative pur-- posesmerely, and thatthe invention, asdelined by the claims hereunto appended, may beotherwise practised without departure from the spirit and scope thereof.

In said drawings Figurel is side elevation, partly in section, of aninternal combustion engine equipped with the invention, showing theparts in position for normal running. a

Fig. 2 is a section on the line 2-2, Fig. 1'.

Fig. 3 is a detail sectional view of the casing and two-way valveillustrated in 1, showing said valve in the position to start theengine.

The internal combustion engine herein shown comprises-a working cylinder10 containing a piston 11 and inclosed by a water jacket 12 forming apart of the cooling system of the engine. Communicating with thecylinder 10 through the. usual inlet valve (not shown) is an intake 13leading from a charge forming device comprising a fuel supply cup 14,fuel nozzle 15 controlled by a needle valve 16, air intake 17, and fuelsupply and overfiow pipes 18 and 19, the former leading from the regularfuel tank (not shown) The engine parts thus far described may be of anyusual or well known form familiar to those skilled in the art and,specifically, form p0 portion of the present vmadamimam ,,GAs'OLENE NGINSZff. 1;

If found necessary 1 ordesirable said casing maybe further 1 cured in place by suitablescrew sor be or otherwise. Within the-*n'ipple 21 bore or passage 23 extendingthrough"an jector or nozzle 2% in'which said' nipp l'te, minates,communicating with 'the interio of "7 the intake l3,'and controlled-"bya needles Qllterminates in a port in'th'eiwallof valve chambercontaining-a two way valve 26, said valve chamber'liaving'fothe'r portscommunicating with passages 24" and leading to threaded sockets29 an d30,'rc

The two-wayjva'lve Qfi 'is pro vided with a port or passage"adaptd'it'o place thepassages 27' and28 alternatively" into communication witli' 'thev'passage when said valve is turnedby*any s'uitable' means, herein shownas anarm 31an'd roil 32. Connected to the socketJ29' is a pif p 33'fleading from a small auxiliary" fuel tank or reservoir 34. To thesocketis corniecte f a pipe 35 terminating in 'a' t ln'e ailedv nipple36 which, when the attachment is appliedfi's received in a tappedopening drilled for that purpose in the wall of the water jacket 12. Thepipes 33 and 35 may be made of any suitable number of lengths andfittings of stock pattern in accordance with the requirements imposed bythe design and location of the engine.

The operation is as follows: The regular fuel tank (not shown) of theengine is filled with kerosene instead of gasolene,

plied to the tank 34. To start the engine, the needle valve 16 isclosed, the needle valve 25 opened, and the two-way valve26 turned intothe position shown in Fig. 3, thereby placing the passage 27 incommunication with the passage 23 and closing the passage 28. G'asolenefrom the tank 34 will there I upon flow, through the pipe 33, to the,nozzle 24, and the engine may be started in the usual manner, the onlydifference being that the fuel is delivered, by the nozzle 24 in steadof by the. nozzle 15. After the enpassage 23, and closing the passage27,

from the tank 3i.

thereby cutting off the supply of gasolene Fuel (in this instance,however, kerosene instead of gasolene). is now drawn from the regularfuel tank and discharged through the nozzle 15 in the usual manrna. Atthe same time hot water from the water jacket is drawn through the pipe36 and discharged by the nozzle 24,.

heating and vaporizing the kerosene and mixlng with the same togetherwith air from the air intake 17, whereby explosive charges are suppliedto the engine cylinder.

It will be seen that the attachment above described may, with slighttrouble and expense, be applied to" any existing engine of the propertype. it being only necessary to drill and tap the openings for thenipples 21 and 35 in the intake and water jacket, respectively, and tomake the required pipe connections. 7

Having thus described my invention, I claim:

l. A kerosene attachment for water-cooled gasolenc engines comprising aninjector provided with means for attachment to the engine intake incommunication therewith,

means for supplying priming fluid to said injector, and a pipe leadingto said injector and having a coupling adapted for connection with thecooling system of the engine,

said tluid supplying means and pipe being alternative COHIIDUIIICHUOH'arranged for with said njector.v
